👉 In mathematics, a sublattice is a subset of some lattice that contains exactly one element for each lattice vector. Sublattices are an important concept in lattice theory and can be used to classify lattices into different types. They are often denoted as L-sublattices or L-matrices. Sublattices are particularly useful in the study of lattice geometry, where they allow for certain calculations involving lattices that do not involve a basis. Sublattice theory
